A DEVICE IN DRAINING GUTTERS

Abstract: A device in draining gutters comprises a gutter member (11) adapted to be imbedded in a hole in a floor in relation to the surrounding floor, connectable to a conduit (6) for draining water, said member being adapted to receive water, and an arrangement for sealing the floor covering (8) in relation to the gutter member, for preventing water from finding its way between the latters. This sealing arrangement has means (23, 24, 25) arranged to seal against the floor covering (8) by bearing on the latter from above around an upper water receiving opening (32) of the gutter member.

Description: A device in draining gutters THE FIELD OF THE INVENTION AND PRIOR ART The present invention refers to a device in draining gutters accord¬ ing to the preamble of the enclosed claim 1. Such draining gutters are arranged in different kinds of spaces for wet conditions, such as e.g. bathrooms and shower rooms, to receive and drain water, such as bath water and shower water. The floor in these rooms is provided with a wet room isolation element in the form of a waterproof floor covering, which can form the very floor covering when it, for instance, is some kind of plastic carpet or can be coated with the very floor covering, if the room for wet condi¬ tions is provided with clinker as the real floor covering. With the ex¬ pression "floor covering" hereinafter and in the claims, is though referred to said waterproof wet room isolation element, which thus can form the very floor surface or not. In draining gutters of this sort it is of the uttermost importance that a seal is arranged, which seal prevents the risk for the occurrance of water damages on floor frame works, the very floor covering or other adjacent building elements. Up to this date, such sealings has been obtained as the floor covering has been cut up in the area of the gutter member, so that sections thereof have been possible to fold down into the gutter member and have been applied to the upper sections of the side wall of the latter, for sealing the floor covering to the gutter member. Thereby, it has been necessary to heat the floor covering to remove the tendencies of the sections that have been folded downwards into the gutter member to creep up from the gutter member, and to form these sections so that they bear tightly on the sidewall of the gutter member. To obtain the desired sealing between the gutter member and the floor covering sections folded downwards a clamp ring has been arranged, said clamp ring being insertable from above into the opening of the gutter member, and said clamp ring executing radial forces against the floor covering sections folded downwards when in inserted position. However, these earlier known devices in draining gutters present important drawbacks. Even when using the above mentioned proce¬ dure for heating the floor covering, which procedure in itself is complicated and forms a considerable drawback, some remaining strains will still exist in said floor covering sections, said strains lending said sections a tendency to strive upwards from the gutter member. In time this unavoidably leads to certain deformations of the floor covering material, such as bulges and the like, through which water that exists in the gutter member is able to, mostly through capillary action, find its way into behind the floor covering sections and in this way cause damages caused by damp on the bottom side of the floor covering, the result of which may be that the complete floor covering of the room for wet conditions must be substituted, or even on surrounding sections in floor frameworks or other building elements, which might lead to substantially more far- reaching and costlier sanitation operations. BRIEF DESCRIPTION OF THE INVENTION The object of the present invention is to provide a device in draining gutters, which sets aside the above mentioned drawbacks of previ¬ ously known such devices and thereby eliminates the risks for dam¬ ages caused by damp originating from the draining gutter in a room for wet conditions provided with such a gutter. According to the invention, the object is obtained by providing the sealing arrangement of the device with means arranged to seal against the floor covering by bearing on said floor covering from above around an upper water receiving opening of the gutter mem¬ ber. Thanks to the sealing means being arranged to bear on the floor covering from above it is no longer necessary to fold said covering down into the gutter member, whereby the floor covering sections located nearest to the gutter member won't have any no¬ ticeable inherent movement or deforming forces. According to a preferred embodiment of the invention the device is provided with members for urging said sealing means towards the floor covering. Hereby, by means of said sealing means, a con¬ stantly good and reliable sealing is obtained. According to another advantageous embodiment of the invention the device is also characterised in that it comprises a ring adapted to surround said opening and, beneath itself, receive the floor covering sections located nearest to the opening, said urging member being arranged to accomplish a force on the ring, said force being directed generally vertically downwards. In this way water located on the floor is thus effectively prevented from flowing beyond the sealing means and reaching the region of the gutter member in any other location than through the upper opening of the gutter member. According to another, very advantageous embodiment of the inven¬ tion the gutter member is designed to be releasably connectable to said conduit and arranged to be removable from the floor after removal of the force of said urging members. Hereby it will thus be possible to remove the gutter member and check its condition at suitable times, especially the look of its different seals. According to yet another embodiment of the invention the device comprises a container-like insert that defines the hole in a floor and, apart from having an opening towards said conduit, is waterproof and adapted to be fixed in relation to the surrounding floor, the gutter member having a smaller dimension laterally and as to depth than the insert and being arranged to form a space between itself and the insert. Hereby is obtained that even if the very improbable would occur, namely that water passes said sealing means, this water will arrive in the space between the gutter member and said waterproof insert, so that thereby no water damage can appear. Thereby the bottom of the insert is preferably provided with a hole which immediately indicates such a leakage by, in a suitable way, draining the water that comes into the space, so that suitable measures for stopping the leakage immediately can be taken. The invention also refers to a method accomplishing a draining gutter in a room for wet conditions according to the enclosed inde- pendent claim as to method. By this method the accomplishment of a draining gutter in a room for wet conditions is considerably facili¬ tated in relation to previously known such methods as the floor-layer only has to lay the floor surface, and applying the hole therein for said draining gutter can wait until it is time for application of heating, water and sanitation connections in the room for wet conditions, as this easily can be done by a non-professional in the floor-laying field. From this follows that the gutter member doesn't need to be arranged in place before the final finishing of the room for wet condi¬ tions through the applying of said heating, water and sanitation con- nections, so that the risks for the gutter member to get broken or hurt in any other way in a building work place are considerably re¬ duced. Further advantages and advantageous characteristics of the inven- tion will appear from the following description and the rest of the enclosed claims. BRIEF DESCRIPTION OF THE DRAWINGS Below, a preferred embodiment of the invention, which is stated as an example, is described with reference to the enclosed drawings, in which: Fig. 1 is a vertical section through a device in a draining gutter ac- cording to a preferred embodiment of the invention, said device being arranged in place in a floor and certain parts having been broken away for the sake of illustration, and Fig. 2 is an exploded, partially sectioned perspective view illustrat¬ ing the design of the different components of the device of Fig. 1. DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION The device has a container-like insert 1 , which defines a hole for a draining gutter, the insert preferably being of a plastic material and being waterproof and adapted to be fixed in relation to the surround¬ ing floor or the floor frame work 2 in connection to the applying thereof to the building in question, the applying of the insert for instance taking place by holding said insert in a requested position and thereafter filling concrete around said insert or fixing it through a connection with adjacent floor frames or the like. The bottom of the insert 1 is formed by a plate 3 which is possible to separate from said insert, which plate is mounted in place simultaneously with the rest of the insert and has a through hole 4, the function of which will be described later. The insert 1 presents an opening in its side wall 5 for receiving a pipe 6 for draining water that flows down into the draining gutter. A tube 7, which is concentrically arranged in relation to the pipe 6 and also opens in the insert 1 , is arranged to take care of water that is possibly leaking out of the pipe 6 and remove it to a shaft in a way known per se. The floor is provided with a floor covering 8, for instance a plastic carpet or some other wet room isolation element, said covering ex¬ tending to the upper limitation of the side wall of the insert 1 and being cut-off there . The floor covering sections 9 located nearest to the gutter opening are adapted to bear on the surrounding upper in¬ sert section 10, which is connected to the sidewall of the insert and extends radially outwards and makes an angle with the floor cover¬ ing and the floor associated therewith by making a larger angle in relation to the horizontal than does said covering, so that the floor covering initially slopes slightly until it reaches the insert section 10 and after that slopes somewhat more towards the inside of the insert section. Thereby, the insert section makes an angle of between 1 ° and 30°, preferably between 3° and 15° with the horizontal. The device further presents a specific gutter member 11 , which is adapted to be arranged immersed into the insert 1 and, thereby, in relation to the surrounding floor and to receive water flowing down thereinto to drain this water via the pipe 6. The gutter member 1 1 is formed by a generally cylindrical container, preferably made of plastic material or stainless steel, which container has smaller dimensions laterally and as to depth than the insert 1 , so that, when arranging the gutter member 1 1 in the insert in the way shown in Fig 1 , a space 12 is formed between these. In its side wall the gutter member 11 presents a tube stump 13 that has an outer diameter which is slightly smaller than the inner diameter of the pipe 6 and on the outside of which surrounding sealing members 14 in the form of conventional O-rings are arranged to form an axial seal between the pipe 6 and the tube stump 13 when the gutter member is brought down into the insert and the tube stump 13 is inserted into the pipe 6, so that water flowing inside the pipe 6 is prevented from reaching the space 12 via the outside of the tube stump 13. Further, the gutter member 11 , in a conventional way, presents a water seal 15, which is formed by a first wall section 16, which extends from a point in the area of the upper edge of the gutter member and down¬ wards, to be ended at a certain distance above the bottom 17 of the gutter member. The first wall section 16 extends continuously between opposite side wall sections of the gutter member. Between these opposite side wall sections of the gutter member a second wall section 33 extends closer to the tube stump 13 and extends from the bottom 17 and up to a substantial vertical overlapping of the first wall section. Hereby, in a conventional way, a water seal is obtained as the water level existing in the gutter member always will be located above the lower limitation of the first wall section 16 and accomplish a delimitation of the air that emerges in the upper opening of the gutter member in relation to water leading sections located downstream the water seal. The device further comprises a ring 18 with a central opening 19 with a lowered support section 20 for receiving a gutter sieve or grating 21 laying thereon, said section 20 extending around said opening 19. The ring 18 is preferably made of sheet material, alu¬ minium or stainless steel and presents a surrounding section 22 that extends axially and defines an opening which has a diameter which is larger than the outer diameter of the gutter member 11 , so that the ring 18 can be axially brought down into the insert 1 with its ax- ial sections while radially surrounding the upper side wall sections of the gutter member 1 1. The ring 18 acutes continuously radially outwards into a point section 23 that presents a generally horizontal upper surface and that has a point angle which is slightly smaller than the angle made by the upper surface of the upper insert section 10 and the horizontal. On the bottom side of the ring 18 two sur¬ rounding sealing means 24, 25, in the form of conventional O-rings, are arranged. The ring also presents a second sealing means 26, also this one an O-ring, which bears on the radially inwards turned wall of the axial section 22. In its upper region the side wall 5 of the insert 1 presents first en¬ gagement members 27 in the form of lists, which are two as to the number and are arranged opposite to each other and to extend in the circumferential direction over an angle distance of, for instance, scantily 90°. The grooves 28 are designed to be able to receive the lists 27 therein. On the radially inwards directed part of the axial section 22 of the ring third engagement members 29, in the form of grooves, are designed in a corresponding way, and on the outer wall of the gutter member fourth engagement members 30, in the form of lists, are arranged and can be brought into engagement with each other. The ring 18 is adapted to co-operate with the insert 1 and the gutter member 11 in the following way to obtain a required seal between the gutter member and the floor covering that surrounds it, which covering does not reach all the way to the opening 32 of the gutter member and therefor not even bears on the gutter member from above: when the gutter member 11 has been brought into the pipe 6 by means of the tube stump 13 so that the gutter member is cen¬ trally located in the insert 1 , the ring 18 is brought downwards in axial direction and with the axial section between the sidewall 5 of the insert and the gutter member 11 , the ring 18 being held in such a turned way that the grooves arranged therein are circumferentially displaced in relation to the lists on the gutter member and the insert, so that the axial section can be pushed beyond these lists to a posi¬ tion in which the lists in question are located in front of the grooves. When this position has been reached, the ring 18 is turned so that the lists 27 and 30 are being brought into the grooves 28 and 29 re¬ spectively. After that, the turning of the ring 18 in relation to the in¬ sert 1 is continued while said lists are running in the grooves in such a direction that the lists of the insert, via the grooves 28, affect the ring 18 in an axial direction downwards, whereby the sealing means 24 and 25 will be pressed into a pre-strained bearing on the floor covering sections 9 located under said means. At the same time, the point of the point section 23 of the ring is pressed against the floor covering 9 and seals in relation to the latter. The second sealing means 26 will be slightly compressed between the outer wall of the gutter member and the axial section of the ring and will thereby pre¬ vent water coming down from the sieve from finding its way to the outside of the gutter member. The lists 27 will thus force the ring 18 into a pre-strained position, while it isn't meant that any transfer of force shall take place between the ring 18 and the gutter member 11 via the grooves 29 and the lists 30, but these members only are adapted to assist the tube stump 13 in holding the gutter member in place in the insert. The screwing of the ring 18 will thus lead to a movement in the axial direction of said ring so that the point of the point section 23 of the ring will be pressed to a pre-strained bearing on the floor covering and thereby function as a sealing means between the ring 18 and the floor covering and prevent water flowing on the floor covering towards the gutter from finding its way down under the ring 18 and thereby having to take the way via the sieve 21 of the gutter and down into the gutter member without getting in the nearness of the location 31 where the floor covering ends. Also the surrounding sealing means 24 and 25 are pressed to a pre-strained bearing on the floor covering sections 9 and serve as an extra security as they, if water actually would trickle between the point section 23 and the floor covering, would prevent this water from getting any further than to these sealing means and thus force said water to find its way to the gutter member via the sieve 21 and not to get in the nearness of the location 31. Would the improbable yet occur, that water at any place, for instance at the second sealing means 26, finds its way be- tween the floor covering 8 and the gutter member 11 this water will reach the space 12 and leave this through the hole 4, so that it will immediately be indicated that a leakage exists in the draining gutter, after which something can be done about this leakage in good time before any real damage has been caused. Even when omitting said leakage indicating hole, water leaking into the space 12 would never be able to rise to the area of the end of the floor covering sections 9 (location 31 ), as this water never would reach higher than to the tube leading to the shaft without being led away to the shaft via this tube. Additionally, the floor covering 8, at the location 31 of the ending thereof, bears on the upper insert section 10 without any in¬ herent tendencies as to deformation, so that the sealing means 24, 25 will make the floor covering seal complete against this insert section 10. Thus, the floor covering doesn't present any section that reaches into or over the opening of the gutter member, and here it even ends at a distance from the very gutter member opening and thereby it is out of question that water reaching the gutter member shall be able to reach the floor covering edge and creep under this, for instance by means of capillary action. The device according to the invention makes it possible to remove the gutter member 11 for an examination by turning the ring 18 in a direction opposite to the tightening direction, to the position in which the lists and grooves go free in relation to each other, after which the ring 18 can be lifted in an axial direction upwards in relation to the insert 1 and the gutter member 11. The fixing of the ring 18 to the insert 1 thus forms a sort of progressive bayonet fixing. When the ring 18 has been lifted away the tube stump 13 and the gutter member 11 can easily be drawn out of the pipe 6 and after that the gutter member is taken away from the insert defining the hole in a floor. Thanks to the possibility of taking the gutter member away, the latter can be taken up for the change of seals, with regular intervals, if that is judged to be necessary, and if the gutter member by any reason would turn out to be leaking during such an examina¬ tion it can be replaced by a new gutter member. During the application of the draining gutter described above in a space for wet conditions one proceeds preferably in the following way: in connection to the application of the floor frameworks 2 the insert 1 is fixed in relation to the former in the position in which one later wishes to arrange the draining gutter. When the floor covering later is laid it is laid over the whole floor by a carpet-layer so that it also covers the upper opening of the insert. Later, when it is time to apply the heating, water and sanitation connections in the room for wet conditions the plumber detects the location of the upper edge of the side wall of the insert and there he cuts the floor covering away. Then he inserts the gutter member in place and applies the ring 18 and tightens the latter. After this the draining gutter is installed. When laying a clinker, the carpet layer, immediately after having applied the floor covering formed by a wet room isolation element, can put said clinker on top of the latter as far as to until the area of the peripheral, upper edge of the insert 1 , so that the ring 18 later can be brought in its place without knocking against the clinker plates. Of course, the invention is not in any way limited to the preferred embodiment described above, but a lot of possibilities as to modifi- cations thereof should be obvious for the one skilled in the art with¬ out the embodiment diverging from the scope of the invention by that reason. For instance, it would be possible to design the different engage- ment members, especially between the insert and the ring, in a number of different ways, for instance to replace male engagement members with female ones and vice versa. Likewise, these mem- bers could have another extent than has been shown in the figures and yet see to that the insert forces the ring in axial direction. It would also be possible to accomplish the forcing of the ring upon the sealing means against the floor covering in another way than by turning of the ring, for instance by some sort of screw union, even if the latter example would be somewhat more complicated than the one illustrated above. In the latter case it would be imaginable to possibly arrange the ring in question in one piece with the gutter member, so that sections of the very gutter member will directly press the sealing means against the floor covering. The conduit from the gutter member could, of course, be connected thereto in a different way, for instance lead downwards from the bottom of the gutter member. The engagement members could also be formed by several turns of co-operating screw threads. Instead of the O-rings bearing on the floor covering silicon glue or the like applied thereon could for instance be used as a sealing means and the gutter member could be arranged more permanently in the hole in a floor. Even if water is mentioned above as well as in the claims, the reception of any other liquid in such a draining gutter is of course completely equivalent. With the patent claim definition "bearing on from above" is only meant that the vector of the bearing force has a vertical component which is larger than the horizontal one.
